Geomagnetic surveys have been carried out over a sample of 30 cropmark sites in the vicinity of Traprain Law, comprising Phase 1 of the Traprain Law Environs Project.

In the majority of cases (23 out of 30), the surveys have confirmed the presence on the ground of the enclosures shown on aerial photographs, often with very clear results. In a number of cases, the surveys have produced evidence of probable internal and/or external features which were not immediately visible on air photographs, while in other cases, the presence of these additional features has been confirmed. Several of the sites investigated appear to represent more than one phase of archaeological activity.

In the 7 cases where cropmark sites have not been readily identified, this appears to be due to a number of factors. In only one instance does the underlying igneous geology appear to be the main factor; while in several cases, anomalies not immediately relatable to the previous cropmarks were detected and might well prove be of archaeological significance.

The work reported here brings to a conclusion Phase 1 of the Traprain Law Environs Project.

A project investigating the nature and development of later prehistoric and Roman Iron Age settlement in a 15 by 10 km block of landscape around the major fortified hilltop site at Traprain Law in East Lothian.

An interpretative transcription, or mapping, of information on oblique aerial photographs was produced on 12 April 2019.

The location, classification and period of this site have been reviewed.
